The Tomy Tutor, originally sold in Japan as the Pyūta (ぴゅう太?) and in the UK as the Grandstand Tutor, is a home computer produced by the Japanese toymaker Tomy. It was architecturally similar, but not identical, to the Texas Instruments TI-99/4A, and used a similar 16-bit CPU. The computer was launched on the UK and European markets in late 1983. Outside Japan, however, sales were not significant.
